I suggest you read the Quran. It might change your mind on violence coming from what people read..
Christians were more brutal than Muslims 1000 years ago but Christians learnt how to modify their religion through history.
Muslims have not learnt it yet but they will!
I have read Qoran and I know how it sounds but I also understand that Qoran was an advancement for the people of Arabian lands 1425 years ago.
Now it does have severe problems for modern world and 21st century, I know that but my take is that it should be edited or modified.
